You can assign a QAction as "action", this way you can just pass it e.g. plasmoid.action("configure").
However, when assigning a null action as can happen with kiosk restrictions, it would crash
as it assigns m_action the nullptr but never checks for that.
This patch ensures we always have a QAction, creating a new empty one, if neccessary.
Also deletes our own action if an external one is assigned
